<p>PURPOSE:To obtain a catalyst combustion type fluid heating device, capable of both of controlling a catalyst combustion temperature and improving a heat exchanging efficiency and capable of reducing the discharge of NOx. CONSTITUTION:A catalyst combustion type fluid heating device is constituted of a catalyst wall 10, provided with a catalyst reacting surface 11 carrying combustion catalyst, a heat transfer wall 20, arranged approximately under a condition that the wall 20 is opposed to the catalyst reacting surface 11 while retaining a specific interval, a combustion space 30, located between the catalyst wall 10 and the heat transfer wall 20 to burn the premixture gas, and the flowing space 40 of fluid to be heated, which is positioned at the opposite side of the combustion space 30 with the heat transfer wall 20 inbetween. A premixture passage 50 for supplying the premixture into the combustion space 30 is formed at the opposite side of the catalyst reacting surface 11 while pinching the catalyst wall 10.</p> |
